BACKGROUND OF THE INVENTION The present invention relates to pocket doorassemblies and it relates more particularly to a novel prefabricatedpocket door assembly which is adjustable in the field to accommodatedifferent door sizes.

Pocket doors normally include a horizontal track which extends above adoor opening into a compartment or pocket adjacent the opening forslidably supporting the door for horizontal movement between a firstposition across the opening and a second or storage position within thepocket. Originally, such assemblies were built in sites by carpentersbut for reasons of economy and quality these custom-built installationshave been largely replaced by prefabricated assemblies. Since thedesired doorway sizes vary'over a wide range, it has been founddesirable to make such assemblies adjustable in size. Such assemblieshave not, however, been entirely satisfactory from the standpoints ofcost and ease of installation. For example, some such assembliesrequired that steel hanger rails to be cut to size by the carpenter orother person installing the door. Others employed relatively expensivetelescoping rail channels.

SUMMARY OF THE INVENTION An object of this invention is, therefore, toprovide a new and improved prefabricated pocket door assembly.

Another object of this invention is to provide a novel track assemblywhich is adapted for use in a pocket door installation.

In order to hang a sliding door so that it does not spuriously come oifthe track, it has been found desirable to provide two-part hangers, onepart of which is secured to the top of the door and hooks onto thesecond part which is slidably secured to the overhead track or rail.Where the second part has its center of gravity offset from the trackengaging portion thereof, the second part has tended to tilt to one sidebefore the door is htmg therefrom. As a consequence, it was frequentlydiflicult to hang the door onto the second hanger part.

Therefore, a further object of this invention is to provlde a new andimproved means for preventing such fianger parts from tilting in thetrack before the door is ung.

Briefly, the above and further objects of the invention are realized inaccordance with the present invention by providing a pocket door frameassembly including a pair of rails each having a mounting web portionadjustably connected to a mounting bracket in co-planar, spacedapartrelationship so that at least one of the rails may be loosened to moveit longitudinally with respect to the opposite rail into an adjustedposition, whereby the overall length of the pocket door frame may beadjusted for accommodating variousdifferent size doors. Also, whentwo-part hangers are employed with the track assembly, for the purposeof limiting the tilting of the track-engageable roller part prior tomounting the door on the track assembly, the track structure is providedwith a mounting bracket having a depending abutment member to limittilting of the roller part of the door hanger, or alternatively, theroller part may be provided with an abutment member for contacting theopposite rail to limit tilting of the roller part. Furthermore, sincethe two rails used with the hangers are identical, manufacturingtechniques and inventory procedures are more economical and simplified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawingsand more particularly to FIGS. 1, 2 and 3, thereof, there is shown apocket door installation 10 including an opening or doorway 11, a pocket13 and a door 14 slidably supported on an overhead track assembly 15between a closed position within the opening 11 and an open or storageposition within the pocket 13. Although the prefabricated. pocket doorassembly may be attached to the building in several different ways, forpurposes of illustration an overall frame which may be built fromtwo-by-fours includes a stud 17 defining one side of the opening 11 anda stud 19 at the rear end of the pocket 13. It will be understood thatthe stud 17 is merely the framing member and in the final installationwill be covered in the usual manner. A header 22 is secured to the stud17 and 19 a substantial distance 3 above the track 15 to maintain thestuds 17 and 19 in the vertical position.

As is more fully described hereinafter, the track assembly 15 includes apair of rail members 23 and 24 for respectively supporting a pair ofhangers 26 and 28 which are attached to the top edge of the door 14. Therails 23 and 24 are each slightly greater in length than the width ofthe door 14 and the rail 23 is fixedly secured at its end to a headerend bracket 30 which is in turn attached to the stud 19 and the rail 24is fixedly at tached at its end to a header end bracket 31 which is inturn attached to the stud 17. The rails 23 and 24 are connected togetherby means of a bracket 32 and a bracket 33. When assemblying the door,these brackets 32 and 33 are loosened and the rails 23 and 24 areextended in a longitudinal direction relative to one another such thatthe brackets 30 and 31 respectively abut the studs 19 and 17. With therails 23 and 24 being level with the horizon, the header brackets 30 and31 are then secured to the respective studs. The brackets 32 and 33 arethen tightly secured to the rails 23 and 24 to hold them in the properrelative position.

The bracket 32, in addition to securing the rails 23 and 24 together inthe adjusted position, also provides a support for a pair of split studmembers 34 disposed on opposite sides of the track assembly. The splitframe member 34 includes a metallic channel member having reentrantmarginal flanges for retaining a wood nailing strip 36 therein and isprovided with a plurality of longitudinally spaced apertures in the webthereof for receiving screws which attach the top of the stud 34 to thebracket 32. A footplate 37 which may be secured as by nailing to thefloor includes means for securing the bottom of the nailing strip 36thereto. The bracket 33 also functions to support a similar split studmember 38 which is also secured at the bottom to a footplate 37 which isin turn fastened to the floor. The split stud 38 also serves as theother jamb member for the doorway 11. As is more fully describedhereinafter, a pair of header nailing strips 39, suitably formed ofwood, is secured over the opening 11 to the bracket 33 and to the headerend bracket 31. It may thus be seen that the split stud members 34 and38 and the header strip 39 provide a convenient means to which wallboardor other sheet material may be secured for completing the installation.

Referring now to FIG. 4, it may be seen that the header end bracket 30which is located within the pocket 13 is a generally channel-shapedmetallic member having an upstanding mounting flange 41 and a pair ofapertured end flanges 42. The flange 41 is provided with a pair ofapertures 43 for receiving mounting screws and it is further providedwith a centrally disposed keyhole slot 44 whereby the bracket 30 may behung on a nail during initial installation of the track assembly 15.

The rails 23 and 24 are identical and may be cut from a single metallicextrusion and, as shown, the rail 23 includes a concave roller-receivingflange 46 and a mounting flange 47. The rail 23 is secured to thebracket 30 by means of an apertured plate 48 disposed under the flange47 and a machine screw 49 which extends through the aperture in theplate 48 and is threadedly received in an aperture 51 in the web of thebracket 30.

The header end bracket 31 is also generally channelshaped and includesan upstanding mounting flange 52 provided with a centrally disposedkeyhole slot 53 and a pair of holes 54 for receiving mounting screws.The web of the bracket 31 is provided with a threaded hole 56 whichreceives a machine screw 57 which extends through an aperture 58 in abracket plate 59 disposed beneath a mounting web 61 of the rail 24 tosecure it to the bracket 31.

The bracket 32 is channel-shaped and includes openings 62 in the sideflanges thereof for receiving the mounting screws which attach the splitstuds 34 thereto and a threaded aperture 63 in the web thereof forreceiving a machine screw 64 which extends through an aperture 65 in amounting plate 66 which underlies the web 47 of the rail 23. Dependingupon the size of the opening 11, the plate 66 may also underlie the web61 of the rail 24 thereby to secure it to the bracket 32 also.

The bracket 33 is also generally channel-shaped and is provided with athreaded hole 67 in the web thereof for receiving a machine screw 68which extends through a hole 69 in a mounting plate 71 which underliesthe webs 47 and 61 of the rail members to secure them to the brackets33. The side flanges of the bracket 33 are provided with openings 72 forreceiving screws for attaching the split jamb members 38 thereto. Inaddition, the bracket 33 is provided with a pair of oifturned tabs 73which overlie the vertical edges of the nailing strip 39 and areprovided with opening 74 for receiving rails or other fastening elementswhich extend into the nailing strip 39. A second pair of tabs 76 arestruck out of the side flanges of the bracket 33 and overlie the topedge of the nailing strip 39 and are apertured to receive fasteningelements such as nails or drive screws.

Mounted approximately midway of the opening 11 is a further bracket 77which is generally channel-shaped and provided with a tap hole 78 in theweb thereof for receiving a machine screw 79 which extends through ahole 81 in a mounting plate 82 disposed beneath the webs t7 and 61 ofthe rails to secure them to the bracket 77. A pair of tabs 83 are struckout of the side flanges of the bracket 77 and are disposed in ahorizontal plane substantially flush with the web of the bracket and areapertured to receive nails or the like which extend downwardly to thetop edge of the nailing strip 39.

As best shown in FIG. 5, the nailing strips 39 are provided with sawcutgrooves 84 which extend into the inner faces of the nailing strips 39 inan upward direction. These grooves 84 extend throughout the length ofthe nailing strips 39 and may be readily cut therein at the factory. Asshown in FIG. 4, the bracket 77 includes a pair of struckout tabs 86which extend from the side flanges of the bracket at an angle equal tothe angle at which the grooves 84 are cut in the nailing strips 39. Inlike manner, the header end bracket 31 is provided with a pair ofstruckout tabs 87 to be received in the grooves 84 in the nailing strips39. Accordingly, the brackets 77 and 31 are slidably disposed relativeto the nailing strips 39 prior to there being secured to the nailingstrips by means of nails or the like extending through the tabs 83 onthe bracket 77 and a pair of similar tabs 88 on the bracket 31. Withthis construction, the brackets 77 and 31 may be spaced from the bracket33 at the desired positions for thewidth of the opening 11 and theportions of the nailing strips 39 which extend beyond the end of thebracket 31 may be readily cut off. Thereafter, the brackets 77 and 31may be secured to the nailing strips 39 by drive screws or the like.

Considering now the door hangers 26 and 28 in greater detail withreference to the drawings, the hangers 26 and 28 are similar to oneanother and are two-part hangers for conveniently connecting the door 14to the track assembly 15. For purposes of plumbing the door 14, at leastone of the hangers may be adjustable to permit the door 14 to be movedinto an adjusted position relative to the track assembly 15 and the stud17 and to be maintained in the adjusted position. For a detaileddescription of a two-part door hanger having means for adjusting thedoor, reference may be made to the above cited copending applicationentitled Door Hanger for a Sliding Door.

As shown in FIG. 5, the hanger 28 includes a roller member 89 having aroller 90 joumaled for rotation thereon and having an opening or slot 92therein, and a doorengageable member 93 having a base 94 and anupstanding hook 96 receivable in the opening 92. The roller 90 rollsalong a concave flange 97 of the rail 24. The base 94 0f thedoor-engageable member 93 is attached to the top edge of the door 14 bymounting screws 98. When connecting the door 14 to the track assembly15, the roller member 89 is first inserted in slideable engagement withthe flange 97 and then the door-engageable member 93 is attached to thetop edge of the door 14. Thereafter, the hook 96 is manipulated intoengagement with the roller member 89.

In order to prevent the roller members of the hangers 26 and 28 fromtilting out of engagement with the concave flanges of the rails 23 and24 before the door-engageable members are connected to their rollermembers, in accordance with one embodiment of the invention as shown inFIGS. 3-5 and 7, the clamping plate 71 includes a depending tab 99 whichextends downwardly opopsite the marginal edge of the flange 46 and theclamping plate 59 includes a depending tab 101 which extends downwardlyopposite the marginal edge of the flange 97. Before connecting the door14 to the track assembly 15, the roller members of the hangers 26 and 28are placed in engagement with the respective rails 23 and 24 oppositethe respective depending tabs 99 and 101. As shown in FIG. 5, due to itsoffset center of gravity, the roller member '89 can tilt in a clockwisedirection before the door-engageable member 93 hooks onto the rollermember '89. However, as shown in FIG. 5, the tab 101 limits tilting ofthe roller member 89.

According to another embodiment of the present invention, as shown inFIG. 6, a header end bracket 102 which may be used for the same purposeas the header end bracket 31 limits tilting of a roller member in thesame manner as the bracket 31. The bracket 102 is generallychannel-shaped and includes an upstanding mounting flange 103 providedwith a centrally disposed keyhole slot 104 and a pair of holes 106 forreceiving mounting screws. A threaded hole 107 in the web of the bracket102 is provided for receiving a machine screw (not shown) which extendsthrough an aperture in a rectangular bracket plate (not shown) disposedbeneath the mounting web 61 of the rail 24 to secure it to the bracket102. The bracket 102 is provided with a pair of struckout tabs 108, eachof which is disposed in a horizontal plane substantially flush with theweb of the bracket in the same manner as the tabs 88 of the end mountingbracket 31. A pair of struckout tabs 109 extend from the side flanges ofthe bracket 102 in the same manner as the tabs 87 of the bracket 31. Astruckout tab 110 extends downwardly from the web of the bracket 102substantially opposite the marginal edge of the flange 97 to limittilting of the roller member 89 in the same manner as the tab 101.

According to a further embodiment of the invention, in order to limittilting of the roller members prior to mounting the door, either one orboth of the hangers 26 and 28 may be provided with an abutment member,such as a shoulder stud 111, as shown in FIG. 7, which is fixedlyconnected to the hanger 26 by any convenient technique, such as welding.The shoulder stud 111 extends from a roller member 112 of the hanger 26over the marginal edge of the opposite flange 97 of the rail 24 to limittilting of the roller member. Should the roller member 112 tilt in acounterclockwise direction as viewed in FIG. 7, the shoulder stud 111engages the marginal edge of the flange 97 to prevent further tilting ofthe roller member 112. With the shoulder stud 111, the roller member 112may be initially placed at any convenient point along the rail 24 priorto mounting the door 14 without regard to the location of the mountingbrackets.

Installation procedure In order to install the pocket door installation10, after loosening each of the clamping plates for the brackets exceptplate 48, the end bracket 31 is slid along the headers 39 as guided bythe slots 84 therein to a position spaced from the bracket 33 tocorrespond to the width of the opening 11, and then the portions of thenailing strips 39 extending beyond the end of the bracket 31 are cutoil. Thereafter, the bracket 77 is slid to a position mid-way betweenthe bracket 33 and the bracket 31. The brackets 77 and 31 may then besecured to the nailing strips 39 by drive screws or the like. The rail24 is secured to bracket 31 by plate 59.

After inserting a nail or the like in both of the studs 17 and 19 at theproper height so that the track assembly 15 can accommodate the door 14,the end bracket 31 is hooked on the nail in the stud 17 and the rails 23and 24 are extended longitudinally relative to one another until the endbracket 30 abuts the stud 19 so that the end bracket 30 can be hooked onthe nail in the stud 19. Thereafter, the bracket 32 is moved into aposition mid-way between the end bracket 30 and the bracket 33. With therails 23 and 24 being level with the horizon, the end brackets 30 and 31are then secured to the respective studs 19 and 17. Thence, each of theclamping plates are tightened to secure the rails 23 and 24 to thebrackets.

Next, the split suds 34 and 38 are connected to the foot plates 37 andthe brackets 32 and 33. Wallboard or other sheet material is thensecured to the split stud members 34 and 38, the header strips 39 andthe other frame members for completing the installation of the pocketdoor frame.

For the purpose of connecting the door 14 rollable engagement with theoverhead track assembly 15, the roller members 89 and 112 are placed inengagement with the respective rails opposite the depending tabs 101 and99 of the mounting brackets 31 and 33, respectively. The door-engageablemembers of the door hangers 26 and 28 are then secured to the top edgeof the door 14 at the same distance apart as the roller members 89 and112. The door 14 is then manipulated into engagement with the rollerhangers 26 and 28. For purposes of plumbing, the door 14 may then beadjusted relative to the track assembly 15 and the stud 17. In order todo this, the door 14 is slid completely into the pocket 13 and theposition of the jamb side of the door 14 is adjusted relative to thetrack assembly 15. Thereafter, the door 14 is slid into the opening 11until the jamb side of the door 14 abuts the stud 17, and the pocketside of the door 14 is adjusted so that the jamb side of the door 14 isflush with the stud 17 In view of the foregoing description, theadjustable pocket door assembly in accordance with the present inventionprovides an assembly which can accommodate various different size doors.The clamping plates on the mounting brackets may be loosened so that oneof the rails may be moved longitudinally with respect to the oppositerail into an adjusted position to accommodate a given size door.Furthermore, various diiferent techniques have been provided inaccordance with the present invention to assist in mounting the dooronto the track assembly by limiting the tilting of the roller member ofthe two-part door hangers.

While there have been shown and described and pointed out thefundamental novel features of the invention, it will be understood thatvarious omissions and substitutions and changes in the form and detailsof the assembly illustrated and in its operation may be made by thoseskilled in the art, without departing from the spirit of the invention.It is the intention, therefore, to be limited only as indicated by thescope of the following claims.
